COMBINATION-TOOL- Specification of Letters Patent.

Patented May 15, 1906.

Application filed October 28, 1905. Serial No. 284,791.

To all whom it may concerw Be it known that we, JOSEPH P. McGIN- NITY, a resident of the city of New York, borough of Manhattan, in the county and State of New York, and ELISHA H. WVINKLER, a resident of Krebs, District No. 15, Indian Territory, citizens of the United States, have invented a new and Improved Combination- Tool, of which the following is a full, clear, and exact description.

This invention relates to combinationtools, and especially to a tool which combines the functions of a brace and a wrench.

The object of the invention is to simplify the construction of a combination-tool for this purpose; and a special object of the invention is to provide means for securing the handle of the brace to the spindle thereof when said handle is being used in connection with. the wrench.

The invention consists in the construction. and combination of parts, to be more fully described hereinafter and definitely set forth in the claims. 1

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the combination-tool and representing the same when used as a brace. Fig. 2 is a side elevation showing a portion of the brace disconnected from the other parts thereof and readjusted to constitute a wrench. Fig. 3 is a view similar to Fig. 1, but representing portions of the mechanism incross-section; Fig. 4 is a se'ction taken on the line 4 4 of Fig. 3 and representing the joint for attaching the chuck end of the brace. Fig. 5 is a section through the bar of the wrench and showing the inner face of the fixed jaw thereof, and Fig. 6 is a crosssection on the line 6 6 of Fig. 3 and illustrating the means for locking the handle against rotation.

Referring more particularly to the parts, 1 represents the upper arm of the brace, and 2 represents the lower arm thereof. The lower arm 2 is connected, through a ratchet connec tion 3, with a chuck 4 of common form. The manner of connecting the arms 1 and 2 so as to form a brace, as indicated in Fig. 1, will be described more fully hereinafter. The upper arm 1 comprises a bar 5, which terminates in a head 6, which constitutes the fixed jaw of a wrench 7, the movable jaw 8 of said wrench being slidably mounted on the bar 5, as shown. The extremity of the bar 5 remote from the head 6 is enlarged so as to form a bracket 9, in which there is rotatably 1nounted an adjusting-screw 10, and this adjusting screw has a threaded connection with the movable 8, as indicated most clearly in Fig. 3. The bracket 9 is formed with a suitable pocket 11, in which there is mounted a thumb-head 12, said thumb-head being rigidly attached tothe adjusting-screw 10, so as to enable the screwto be rotated as desired.

Projecting laterally from the bracket'Q and integral therewith is provided a spur-segment 13 comprising a pair of oppositely-disposed ears 14, said ears being of substantially circular form and provided on their peripheries with outwardly-projecting spurs or teeth 15. Between these ears 14 is attached a spindle 16, as indicated in Fig. 3, said. spindle being provided with an enlarged head 17 with an opening therethrough for this purpose. Through the opening in the head a suitable pin or bolt 18 passes, as will be readily understood. The body of the spindle 16 is of round form, as shown. Near its lower portion it is provided with screwthreads 19, and beyond this point it is of slightly reduced or tapered form, so as to present a tang 20. Over the spindle 16 there is received a sleeve 21, which sleeve terminates at its upper extemity in an integral head 22. This head on its upper side is provided with notches 23, which are disposed opposite the ears 14 and correspond in position to the spurs or teeth 15, formed thereon. From this arrangement this head is adapted to engage the segment and may be locked thereagainst, so as to hold the spindle rigidly at right angles to the bar 5, as indicated in Fig. 1. The arrangement for locking the spindle thus will be more fully described hereinafter. U on the sleeve 21 there is rotatably mounter a handle 24, the lower extremity whereof is provided with an enlarged bore 25, receiving a ferrule 26, the said ferrule seating against a shoulder 27, as shown. The lower extremity of the aforesaid sleeve 21 is expanded over this ferrule, so as'to retain the same in position, thus holding the handle in place against longitudinal movement on the sleeve, as will be readily understood. Upon the aforesaid threads 19 a nut 28 is received,

as shown, said nut having a reduced neck 29, which passes into the bore 25. The body of this nut is much enlarged and is adapted to afford opportunity for screwing the nut tightly against the extremity of the sleeve 21. In this way the segment 13 is force down against the sleeve 21, so that the notches 23 will receive the teeth 15 of the segment in 10 the manner suggested above. The aforesaid tang projects beyond the lower extremity of the handle 24 and beyond the nut 28. In

order to enable the arm 2 to be attached thereto, the lower extremity of the arm 2 is I 5 formed into a socket 30, as indicated most clearly in Figs. 3 and 4. In one side of this socket a slot 31 is formed, in which a dog 32 is pivotally mounted, said dog being preferably constrained by a spring 33, so that its 20 tip is forced against one of the converging or wedge faces 34 of the tang. The tang 20 at a suitable point on its opposite tapered faces is provided with notches or recesses 35. As

indicated, the dog 32 is provided with a tail 2 5 36, under which the aforesaid spring 33 rests.

WVhen the socket is forced over the tang,

as indicated in Fig. 4, the dog 32 engages either of the notches 35, so as to lock the socket against accidental removal. hen it 0 is desired to remove the socket, it is only necessary to depress the tail 36 of the dog 32,

which releases the dog from the notch with which it is in engagement, enabling the tang to be withdrawn from the socket. The un- 5 der face of the nut 28 is preferably formed with a bore 37, into which the upper extremity of the socket projects when set in position as indicated in Fig. 3.

In Fig. 5 we illustrate the inner face 37 of 40 the fixed jaw 6 of the upper arm 1, and it should be said that the inner face 38 of the movable jaw 8, which lies opposite, is simi larly formed with respect to the features about to be described. These inner faces are provided with oppositely-disposed recesses 39, which present bevel-faces, as shown, di minishing in the direction of the bar 1. These recesses are adapted to grasp the cor ners of a removable shank 40, carrying a knob 41. It should be understood that by screwing the jaw 8 tightly against the jaw 6 the shank 40 is securely held in a vertical position. In this connection it should be stated that the axis of the shank 40 when held as stated is in substantial alinement with the axis of the chuck 4. Under normal circumstances the handle 24 is rotatable when the tool is being used as a brace. It is desirable, however, that means should be provided for locking the handle against rotation when the tool is to be used as a wrench. IVe provide the arrangement illuscated most clearly in Fig. 6.

longitudinally-disposed groove or guideway 42, in which there is slidably mounted a button 43. The said button is provided at one extremity with a projecting pin 44. On the extremity of the handle 24, adjacent to the head 22, we provide a cap or collar 45, which collar is provided with a plurality of openings 46, disposed circumferentially, as indi- These openings are adapted to come into alinement with the pin 44, as the handle is rotated. The body of the button 43 projects outwardly and is adapted to be pressed by the thumb,

so as to slide the same up or down, as will be readily understood. I/Vhen one of the openings 46 is in alinement with the pin 44, the button 43 may be forced downwardly, so as to project the pin 44 into the said opening, and in this way lock the handle of the head 22, so that it cannot rotate. e prefer to provide a plurality of the openings 46, so that delay in bringing about an alinement,

as suggested, is avoided. As indicated most clearly in Fig. 6, the guide-slot 42 is enlarged below or undercut, so as to prevent the button 43 from being removed laterally.

The attachment of the knob 41 to the shank 40 will now be described. For this purpose the upper extremity. of the shank 40 is provided with a reduced tip 47, which is 5 provided with screw-threads, as shown. Upon this tip a hub 48 is rotatably mounted, and this hub is secured in place by a nut 49, which fastens upon the tip 47. Upon the hub 48 the knob 41 is rigidl secured. The I00 hub 48 is preferably provi ed at its lower side with a bore 50, which receives the upper portion of the body of the shank. From this arrangement evidently the knob 41 may be rotated freely on the shank, but cannot be IO 5 pulled upwardly from the same.

When the parts have the relation shown in Figs. 1 and 3, the device is adapted to be used as a ratchet-brace. If it is desired to use the device as an ordinary brace, not inno volving a ratchet, the shank 40, together with the knob 41, may be detached from the up per arm 1 and placed in position in the chuck 4, which chuck is also adapted to receive the bit or screw-driver. WVhen it is desiredto use the device as a wrench, the lower arm 2 is detached from the tang 20 in the manner suggested above. The nut 28 is then unscrewed, so as to loosen the engagement between the notches 23 and the segment 13.120 The handle 24 and its spindle 16 are then rotated around to such a position as shown in Fig. 2, so that the axis of the spindle lies sub stantially parallel with the bar 1. The nut 28 is then tightened into position again, so as I2 5 to securely fasten the spindle to the segment in this new position. After fastening the spindle as suggested the button 43 is then operated, so as to lock the handle 24 to the sleeve 21, as described above. The shank 40 I 0 and the knob 41 having been removed from the jaws 6 and 8, the device is then adapted for use as a wrench. In this connection special attention is called to the function of the button 43 in securing the handle 24 rigidly against rotation. A rigid handle of this kind is highly desirable in a wrench; but it should be rotatable in a brace. In order to maintain the button 43 in either of its extreme positions, its outer face is provided with two notches which are adapted to receive the extremity of a leaf-spring 43*, said spring being rigidly secured to the collar 45. It should be observed that the segment 13, in connection with the head 22, constitutes a joint capable of being fixed so as to maintain the handle 24 in any angular position desired with respect to the arm 1. The possibility of connecting the handle in various angular positions is most desirable when the device is being used as a wrench.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. A combination-tool comprising a jointed member with jaws constituting a wrench, a removable shank held in said jaws and carrying a rotatable knob, and a detachable arm adapted to be secured to said first memo ber and carrying a chuck.

2. A combination-tool comprising a bar having a fixed jaw, a movable jaw mounted thereon, a segment carried by said bar, a spindle joined to said segment, a handle carried by said spindle, an arm detachably con- 35 nected to said spindle and carrying a chuck,

a shank removably held between said jaws, and a knob rotatable on said shank.

3. A combination-tool to be used as a brace and as a Wrench and having a spindle, a 0 sleeve surrounding said spindle, a normally rotatable handle carried on said sleeve having an opening in the extremity thereof, and a slidable button on said sleeve adapted to engage said opening to lock said handle to 5 said sleeve.

In testimony whereof we have signed our names to this specification in the presence of subscribing witnesses.
